Mice come indoors searching for food, warmth, and shelter. Kitchens provide all three, especially if food is left out or there are small gaps for mice to enter. Usually, if you see one mouse, there may be more nearby or on their way, since mice reproduce rapidly. A female mouse can have 5–10 litters per year with up to 14 pups each — a single mouse spotted in your kitchen can become a colony of 50+ within months. In New Hampshire, mice are most active in kitchens during fall and winter when they move indoors seeking warmth and food.

Steps to Follow Right After Seeing a Mouse

• Don't Panic. Mice are common household pests and can be handled with the right steps.
• Remove all food from countertops and open areas. Store food in sealed, hard containers (metal, glass, or thick plastic, not bags or boxes).
• Clean up immediately. Wipe down surfaces, vacuum or sweep crumbs, and empty your trash can each night.
• Look for evidence. Check along walls, behind appliances, and inside cabinets for mouse droppings (tiny black pellets), chewed food packaging, or gnaw marks. These clues help you spot where the mouse travels.

Blocking Entry Points to Stop More Mice

• Inspect the kitchen for holes and gaps. Look around pipes, behind appliances, and along baseboards. Mice can squeeze through holes as small as a dime.
• Seal holes with steel wool and caulk. Steel wool blocks mice from chewing through. Apply caulk or foam over the wool to keep it in place. Larger gaps may need metal screens or cement.
• Check doors and windows. Make sure there are no gaps at the edges or beneath doorways. Use weather-stripping for a tight seal.

Best Ways to Catch or Remove the Mouse

• Use traps, not poison, in kitchens. Snap traps are effective and humane when used properly. Place traps along walls, behind appliances, and where you've seen mouse activity. Peanut butter or chocolate makes good bait.
• Avoid using poison indoors. Poisoned mice may die in walls or hard-to-reach places, causing odor and further problems.
• Check and reset traps daily. If you catch a mouse, wear gloves to dispose of it in a sealed bag, and clean the area well.

Cleaning and Disinfecting After Mice

Mouse droppings and urine can carry diseases, so it's important to clean up safely. The CDC recommends never sweeping or vacuuming dry rodent droppings, as this releases Hantavirus particles into the air. Always spray with disinfectant or bleach solution first and wait 5 minutes before wiping. Mice in New England, including NH, can carry Hantavirus — proper cleanup prevents exposure.

• Wear disposable gloves.
• Do not sweep or vacuum droppings dry. Spray droppings and nesting materials with a disinfectant or bleach solution first, then wipe up with paper towels. Dispose in a sealed bag.
• Wash hands thoroughly after cleaning.

If the infestation was large (more than a few droppings per room), professional decontamination is recommended over DIY cleanup.

Preventing Future Mouse Problems

• Keep all food sealed. Mice are attracted to open food, pet food, and garbage.
• Empty trash regularly and keep bins closed.
• Clean up crumbs, spills, and food scraps immediately.
• Maintain your home. Re-check and re-seal holes every few months. Mice are persistent and will try new entry points.
